にするためである。The damper wing 3 is a disc-shaped member, and is on the indoor side of the building (arrow A
A spherical portion 8 that bulges to the side) is formed in the inside, and a contact edge 9 is bent and formed around this spherical portion 8 in an inclined state toward the indoor side. The spherical portion 8 is provided in order to efficiently receive the differential pressure between the indoor and outdoor areas, which will be described later.
このダンパ翼3は、球面状部8の中心に形成した軸受け
部11に摺接・挿通する軸部材12にて支持されつつ矢
示Bの如く進退動するようになっているもので、圧縮バ
ネ13により建物室外側(閉方向)に付勢されている。The damper blade 3 is adapted to move forward and backward as shown by an arrow B while being supported by a shaft member 12 which is slidably contacted with and inserted into a bearing portion 11 formed in the center of a spherical portion 8. It is urged by 13 toward the outside of the building (close direction).
軸部材12は給気路形成体2に固定した支持アーム14

13の付勢力に抗して室内側(矢示A側)へ退動し、当
接受け縁7と当接縁9との間にラッパ状の通気路Pが形
成され、外気Eが給気されるようになる。When the ventilation fan is operated in a room where the other end of the ventilation duct D is exposed to exhaust the room, the inside of the ventilation duct D is decompressed as well as the inside of the ventilation duct D is decompressed. Then, the damper blade 3 retreats toward the indoor side (arrow A side) against the urging force of the compression spring 13 due to the pressure difference with the outside air, and the trumpet between the contact receiving edge 7 and the contact edge 9 is increased. The air passage P having a shape is formed, and the outside air E is supplied.
この時、通気路Pは、そのラッパ状の形状故に外気Eの
流れを整流化させる。そして、この整流化された外気流
